When Tricia Miles's assistant manager Pixie finds homeless vet Susan Morris's body behind the bookstore, Pixie's checkered past makes her the prime suspect. Armed with an earring found at the scene of the crime, Tricia discovers Susan was involved in a scandal right before retiring from the Navy. With family drama brewing in the background and all of Stoneham convinced her manager is a murderer, Tricia knows she has to get to the bottom of the case—her 14th, after A Killer Edition—before Pixie is sunk.
